What It Does
Having corrected directional mistakes with the Gear Effect Grooves, our next task was to help golfers overcome the other big problem caused by miss-hits:
A loss of distance.
We did it by injecting a new-age compound into the Pyramid iCOR’s clubhead, concentrating on the heel and toe areas behind the insert.
The compound flexes on impact, raising the Coefficient of Restitution (COR) across the putter’s face – and a higher COR means less energy loss on miss-hits.
Put another way: The Pyramid iCOR’s insert is one gigantic sweet spot.
What’s more, the added weight surrounding the center boosts the Pyramid iCOR’s Moment of Inertia (MOI), so it’s more stable on poorly struck putts.
In fact, the iCOR’s MOI is about 20% higher than the original Pyramid’s.
All of which means you can miss the dead center – by a fair margin – and your putt will lose little if any distance.
Let’s dig a little deeper into the science, and the painstaking process of picking the perfect material:
With the putter (as with any club), the sweet spot is the area where maximum energy is transferred from the club to the ball. By striking it, you achieve max distance for whatever speed the club is traveling.
Miss the sweet spot toward the toe or heel and energy is lost.
Hence, even a small miss-hit can cause a putt to come up short. And the bigger the miss-hit, the more energy (distance) you lose.
Then there’s this: The longer the putt, the longer your stroke… and the more likely you are to miss the sweet spot.
Even worse, your miscues tend to be farther from center on a longer stroke.
That’s one reason putts from 25 feet or more often come up way short.
And that’s the issue we set out to solve.
The key was to find a material that would:
Deliver the best rebound (energy transfer) on off-center hits…
Provide the ideal amount of weight so the Pyramid iCOR Putter wasn’t too heavy or light, AND...
Offer a pleasing sound and feel on impact… because nobody likes a harsh, clangy putter.
As you might expect, there was plenty of trial and error.
In testing various compounds, we found that some worked great at negating distance loss on misses...
But created an off-putting sound or feel.
Others sounded and felt terrific on impact...
But provided minimal help on heel and toe strikes.
Still others delivered the distance correction we wanted...
AND the pleasing sensation all golfers crave...
BUT… They made the iCOR Putter so heavy, it may as well have been a sledgehammer.
It was frustrating, to say the least.
We kept our noses to the grindstone, though...
We found our “Goldilocks” material.
It gave the Pyramid iCOR the perfect weight.
With exquisite sound and feel.
Most importantly, it made distance control nearly automatic.
On all lengths of putts.
Even on the worst miss-hits.
We call this material “Speed Correcting Compound” – because it ensures that your off-center strikes will roll almost as far as your solid ones.
By “almost as far,” we mean within inches… if not fractions of an inch.
Combine the Pyramid iCOR’s Speed Correcting Compound with its Gear Effect Grooves and you get a putter with unmatched directional accuracy and distance control.
